- Sir Benjamin Dyce: [gesturing to Moonbase window] Look out there, all of you. What do you see?
- Michel Lebrun: The Earth.
- Sir Benjamin Dyce: And can you see your beloved France?
- Michel Lebrun: Yes, not clearly...
- Sir Benjamin Dyce: And can you see where France stops and Germany, Switzerland or anywhere else starts?
- Michel Lebrun: Not with the naked eye...
- Sir Benjamin Dyce: You cannot see that if the soil is as close to your face as this meaningless bit of cloth!
- [throws mini-French flag to the floor]
- Sir Benjamin Dyce: It is only on maps that the colour of one country is different from the colour of the next.
- Michel Lebrun: There is nothing wrong with a man being proud of his own country.
- Sir Benjamin Dyce: There is everything wrong with it!
- Dr. David Caulder: You were wrong, weren't you? Eh? Thank God, you were wrong!
- Sir Benjamin Dyce: Yes, I was wrong. Any man can make a mistake. But mankind, now mankind cannot be allowed one single mistake.
- Sir Benjamin Dyce: I've always held that the last words of mankind will not be the secret name of God but, "What is this knob for?"
- Michel Lebrun: The fourteenth of July! And in Paris there will be singing and dancing in the streets and lots of wine - and here? Here we celebrate with reconstituted calves liver, synthetic potato and H14, a local lunar vegetable so disgusting that nobody's ever bothered to give it a name.
- Bruno Bertoli: Well, at least there's wine, Michel.
- Michel Lebrun: Oh, yes of course, we mustn't forget the wine. Château Mouton Caulder: add two packets of purple powder to five litres of recycled effluent and stir. I wouldn't find it all so revolting if I didn't know how it was made.
- Sir Benjamin Dyce: [On being introduced to Helen Smith] I've always doubted if women have any useful place in science.
- Dr. Helen Smith: I don't think Pierre Curie would've agreed with you.
- Sir Benjamin Dyce: The man was a fool! Any man who is so careless to the material he is researching as to die from it!
- Sir Benjamin Dyce: You are intellectual incontinents! Ideas dribble from you without either volition or control!
